5. AUTO-RP Dynamic election RP
The following rules apply to configuring AUTO-RP
1, PIM mode to be configured as Sparse-dense mode (when the sparse mode does not work, you can work in dense mode, the role of starting backup redundancy)
2, CRP, MA usually use the ring-back port, and need to pass into the IGP
3, MA Loopback port should also be configured as Sparese-dense mode
We're talking here R1 configuration for crp,r2 configured as Ma
